Based on performance demand for Team merchandise will increase and decrease.
So teams putting in good performances will increase their commerce rating and thus income from more demand.
The same for championship winning teams.
This needs to be very dynamic so big drops from low placing and high gains from good finishes, especially to teams taking an unexpected podium.
I think this will add another layer to iGp as we will have fans to cater to and put in good performances for a good financial reward.
